Help needed with Pharoah virus

Hello everybody, i'm new to this site but so far i like the look and the response of how the pages quickly open.. Very slick.

I am only on the internet via the library, so my options for doing things are limited, as most of the solutions suggested to me in the past when, i've had a problem seem to require you to have internet access at home.

My current problem involves a virus i've picked up called Pharoah.exe. I've asked for help on other forums and most of the solutions require me to be online. I've tracked down and deleted most of the files that are creating the problem, but they keep coming back. In essence, the virus is duplicating my file waiting for me to go online, when it will then no doubt transfer all my files to who knows where.

At the moment it is just copying all my files and not corrupting any, it just slows the computer down. But i've been told that it might have a time limit built in which will start deleting my file.
I would like to get rid of this virus before this starts to happen.
Can anybody offer a solution which does not require me to go on line.
I am familiar with going into the registary in order to change things and this would appear to me to be the answer. If I could find the file/program which is recreating the file that i keep on deleting but which keeps coming back, then i think i will have found the cure.
